Group 3A
20
Boron : This element is a atomic number of 5
Aluminum : This element was discovered in 1825 by Hans Christian Oersted
Gallium : This is a Group 3A element with a Atomic Weight of 69.72
Indium : This elements elemental symbol is "In"
Thallium : This element was discovered in 1861 by Sir William Crookes
Metalloid : Boron is the only one of these in Group 3A elements
Iron : Aluminum mixed with this created a very useful alloy that has a low density and resist corrosion
Liquidgallium : Solid gallium floats in this which unusual for a metal
Density : Thallium has the highest of this out of the Group 3A elements
Oxide : Boron can be prepared by the reaction of its _____ with magnesium metal
Bauxite : This is a common ore of aluminum
Alumina : This is the primary mineral in bauxite
Halogens : Group 3A elements react with these to form halides
Catalyst : Aluminum chloride is used as this in organic reactions
Oxides : These are formed when Group 3A elements react with oxygen
Exothermic : Powdered aluminum is a component in some explosives because its reaction is very ______.
Boricacid : this is very poisonous if ingested, the solid is used as an insecticide
molten cryolite : Aluminum oxide is dissolved in this during the Hall-Heroult process
Anodizing : This process helps protect aluminum from corrosion by coating it with aluminum oxide
Corundum : This is a mineral of aluminum oxide, rubies are this
